          Appeal No. 96-2696                                                          
          Application 08/167,415                                                      


               eliminating means coupled to said receiving buffer to                  
          supply said compressed image data to said receiving buffer                  
          after eliminating invalid code for preventing underflow of                  
          data in a send buffer provided in an image coding apparatus.                
               Both of these claims recite "invalid code for preventing               
          underflow of data in a send buffer."  As explained above, in                
          both the prior art system and appellants' invention an                      
          underflow condition is detected in the send buffer and                      
          corrected by inserting invalid code into the output data                    
          stream of the send buffer.
